Description

Technical Field

[0001] This invention belongs to the field of lifting work platform technology, and more specifically, relates to a lifting work platform device for elevator shaft construction. Background Technology

[0002] Before an elevator is put into use, construction work needs to be carried out inside the shaft. However, there is a lack of a dedicated platform for construction personnel to operate in the shaft. Therefore, it is usually necessary to add an additional lifting mobile platform to meet the construction needs. This type of mobile platform generally consists of two parts: a lifting mechanism set at the top of the shaft and a working platform placed inside the shaft. During operation, the lifting mechanism provides power to drive the working platform to move smoothly up and down in the shaft, thereby enabling construction personnel to carry out construction work at different heights in the shaft.

[0003] The following problems still exist with the currently used lifting work platforms: 1. Although some lifting work platforms are equipped with elastic anti-sway structures, swaying still occurs when construction workers are working on the elevator shaft, indicating poor anti-sway effect; 2. Lack of tilt detection function makes it difficult for workers to detect slight tilting of the lifting work platform; 3. Generally, only one lifting mechanism is set up, and when the lifting mechanism stops working due to malfunction, it can easily affect the normal construction of the elevator shaft. Summary of the Invention

[0004] This disclosure relates to a liftable work platform device for elevator shaft construction, comprising a lifting control unit, a connecting lifting unit, an elastic support unit, an anti-sway stabilizing unit, and a tilt warning unit. When construction workers are working inside the shaft, the workers automatically separate from the stepping disc, and four rubber anti-slip blocks brake four rectangular sliding rods. When one of the control buttons is pressed, the intelligent control panel stops the two drive motors, and the alarm inside the intelligent control panel sounds an alarm. The two lifting control wheels rotate simultaneously under the action of two emergency sprockets and chains, which facilitates the normal movement of the lifting construction platform. It allows for timely repair of damaged worm gear reducers and drive motors without affecting normal shaft construction. This solves the problems of swaying during elevator shaft construction, difficulty in noticing slight tilting of the lifting work platform, and disruption of normal elevator shaft construction when the lifting mechanism stops working due to malfunction.

[0009] In at least some embodiments, the elastic support includes: a rectangular sliding rod, a force-bearing roller, and a circular limiting plate a; the rectangular sliding rod is slidably mounted on the lifting construction plate; the force-bearing roller is rotatably mounted on the outer end of the rectangular sliding rod, and the force-bearing roller is in contact with the inner wall of the elevator shaft; the circular limiting plate a is fixedly mounted on the outside of the rectangular sliding rod.

[0010] In at least some embodiments, the elastic support further includes: a circular limiting plate b and a helical spring a; the circular limiting plate b is fixedly installed on the outside of the rectangular sliding rod; the helical spring a is sleeved on the outside of the rectangular sliding rod, and the helical spring a is located between the lifting construction plate and the circular limiting plate a.

[0011] In at least some embodiments, the anti-sway stabilizing component includes: a polygonal rod, a cross-shaped bracket, and a foot pedal disc; the polygonal rod is slidably mounted on the lifting construction plate; the cross-shaped bracket is fixedly mounted on the bottom of the polygonal rod; and the foot pedal disc is fixedly mounted on the top of the polygonal rod.

[0012] In at least some embodiments, the anti-sway stabilizing unit further includes: a rubber anti-slip block, a helical spring b, and a detection button; four rubber anti-slip blocks are provided, and the four rubber anti-slip blocks are fixedly installed on the top of the cross-shaped bracket, and the top of the four rubber anti-slip blocks contacts the bottom of the four rectangular sliding rods; the helical spring b is sleeved on the outside of the polygonal rod, and the helical spring b is located between the lifting construction plate and the pedal disc; the detection button is fixedly installed on the pedal disc, and the detection button is electrically connected to the intelligent control panel.

[0016] 2. In this invention, when construction personnel need to control the two drive motors through the intelligent control panel, the detection button must be pressed. When the two drive motors are working, the construction personnel need to stand on top of the foot pedal disc. When the construction personnel are working inside the shaft, the construction personnel automatically separate from the foot pedal disc. The four rubber anti-slip blocks brake the four rectangular sliding rods, ensuring that the lifting construction plate will not shake when the construction personnel are working, thus improving stability.

[0017] 3. In this invention, when one of the drive motors stops working due to a malfunction, while the other drive motor is working normally, the lifting construction plate will slowly tilt, causing the circular solid seat to slide a certain distance under its own weight. When the circular solid seat slides a certain distance under its own weight, the rectangular pressing rod can press one of the control buttons. When one of the control buttons is pressed, the intelligent control panel controls both drive motors to stop working, and the alarm inside the intelligent control panel sounds an alarm. Furthermore, when the malfunctioning worm gear reducer and drive motor are removed, construction personnel can use an external large wrench to adjust the angle of the corresponding lifting control wheel appropriately, which helps to straighten the tilted lifting construction plate. It also allows construction personnel to connect the lifting control wheel via an external chain and two emergency sprockets. When the malfunctioning worm gear reducer and drive motor are removed for repair, and the other drive motor is working normally, the two lifting control wheels rotate simultaneously under the action of the two emergency sprockets and the chain, which facilitates the normal movement of the lifting construction plate. This allows for timely repair of the damaged worm gear reducer and drive motor without affecting normal shaft construction. Attached Figure Description

[0026] The specific functions of the lifting control unit 100 and the connecting lifting unit 200 are as follows: Since the two lifting control wheels 103 are rotatably mounted on the four support baffles 102, and the output shafts of the two worm gear reducers 105 are connected to the two lifting control wheels 103, and the two drive motors 106 are fixedly mounted on the two worm gear reducers 105, when the intelligent control panel 600 controls the two drive motors 106 to work, the two lifting control wheels 103 rotate. Furthermore, since the four wire ropes 201 are fixedly mounted on the two lifting control wheels 103, and the four wire ropes 201 pass through the shaft connecting frame 101, and the lifting construction plate 202 is fixedly mounted at the bottom end of the four wire ropes 201, when the intelligent control panel 600 controls the two drive motors 106 to rotate forward, the lifting construction plate 202 moves slowly downward; when the intelligent control panel 600 controls the two drive motors 106 to rotate in reverse, the lifting construction plate 202 moves slowly upward, facilitating construction personnel to carry out construction operations at different heights within the shaft.

[0027] In this embodiment of the disclosure, such as Figure 4 and Figure 6 As shown, the elastic support 300 includes: a rectangular sliding rod 301, a force-bearing roller 302, and a circular limiting plate a303; the rectangular sliding rod 301 is slidably mounted on the lifting construction plate 202; the force-bearing roller 302 is rotatably mounted on the outer end of the rectangular sliding rod 301, and the force-bearing roller 302 is in contact with the inner wall of the elevator shaft; the circular limiting plate a303 is fixedly mounted on the outside of the rectangular sliding rod 301; the elastic support 300 also includes: a circular limiting plate b304 and a helical spring a305; the circular limiting plate b304 is fixedly mounted on the outside of the rectangular sliding rod 301; the helical spring a305 is sleeved on the outside of the rectangular sliding rod 301, and the helical spring a305 is located between the lifting construction plate 202 and the circular limiting plate a303.

[0028] The specific function of the elastic support part 300 is as follows: Because the rectangular sliding rod 301 is slidably installed on the lifting construction plate 202, and the force-bearing roller 302 is rotatably installed on the outer end of the rectangular sliding rod 301, the rectangular sliding rod 301 can drive the force-bearing roller 302 to slide; and because the circular limiting plate a303 is fixedly installed on the outside of the rectangular sliding rod 301, and the helical spring a305 is sleeved on the outside of the rectangular sliding rod 301, and the helical spring a305 is located between the lifting construction plate 202 and the circular limiting plate a303, the force-bearing roller 302 is always in contact with the inner wall of the elevator shaft under the action of the helical spring a305, which plays an elastic support role and ensures that the lifting construction plate 202 is basically in a stable state when it is lifted.

[0029] In this embodiment of the disclosure, such as Figure 4 , Figure 5 and Figure 8As shown, the anti-sway stabilizing unit 400 includes: a polygonal rod 401, a cross-shaped bracket 402, and a foot pedal disc 403; the polygonal rod 401 is slidably mounted on the lifting construction plate 202; the cross-shaped bracket 402 is fixedly mounted on the bottom of the polygonal rod 401; the foot pedal disc 403 is fixedly mounted on the top of the polygonal rod 401; the anti-sway stabilizing unit 400 also includes: rubber anti-slip blocks 404, a coil spring b405, and a detection button 406; four rubber anti-slip blocks 404 are provided, and the four rubber anti-slip blocks 404 are fixedly mounted on the top of the cross-shaped bracket 402, and the tops of the four rubber anti-slip blocks 404 are in contact with the bottoms of the four rectangular sliding rods 301; the coil spring b405 is sleeved on the outside of the polygonal rod 401, and the coil spring b405 is located between the lifting construction plate 202 and the foot pedal disc 403; the detection button 406 is fixedly mounted on the foot pedal disc 403, and the detection button 406 is electrically connected to the intelligent control panel 600.

[0030] The specific function of the anti-sway stabilizing unit 400 is as follows: Since the foot pedal disc 403 is fixedly installed on the top of the polygonal rod 401, and the detection button 406 is fixedly installed on the foot pedal disc 403, and the detection button 406 is electrically connected to the intelligent control panel 600, when the construction worker needs to control the two drive motors 106 through the intelligent control panel 600, the detection button 406 must be in the pressed state, so that the construction worker needs to stand on top of the foot pedal disc 403 when the two drive motors 106 are working; and because of the four rubber anti-slip... Block 404 is fixedly installed on the top of the cross-shaped bracket 402, and the top of the four rubber anti-slip blocks 404 contacts the bottom of the four rectangular sliding rods 301. The helical spring b405 is located between the lifting construction plate 202 and the foot pedal disc 403. When the construction personnel are working inside the shaft, the construction personnel are automatically separated from the foot pedal disc 403. The four rubber anti-slip blocks 404 play a braking role on the four rectangular sliding rods 301, ensuring that the lifting construction plate 202 will not shake when the construction personnel are working, thus improving stability.

[0031] In this embodiment of the disclosure, such as Figure 9 and Figure 10As shown, the tilt warning unit 500 includes: a U-shaped mounting frame 501, a polygonal shaft 502, and a circular solid base 503; the U-shaped mounting frame 501 is fixedly mounted on the bottom of the cross-shaped bracket 402; the polygonal shaft 502 is fixedly mounted on the U-shaped mounting frame 501; the circular solid base 503 is slidably mounted on the outside of the polygonal shaft 502; the tilt warning unit 500 also includes: a helical spring c504, a control button 505, and a rectangular pressing rod 506; two helical springs c504 are provided, and the two helical springs c504 are sleeved on the outside of the polygonal shaft 502, and the two helical springs c504 are located on both sides of the circular solid base 503; two control buttons 505 are provided, and the two control buttons 505 are fixedly mounted inside the U-shaped mounting frame 501, and the two control buttons 505 are electrically connected to the intelligent control panel 600; the rectangular pressing rod 506 is slidably mounted on the U-shaped mounting frame 501, and the top of the rectangular pressing rod 506 is fixedly connected to the circular solid base 503.

[0032] The specific function of the tilt warning unit 500 is as follows: Because the circular solid base 503 is slidably mounted on the outside of the polygonal shaft 502, and two helical springs c504 are sleeved on the outside of the polygonal shaft 502, with the two helical springs c504 located on both sides of the circular solid base 503, when one drive motor 106 stops working due to a malfunction, and the other drive motor 106 is working normally, the lifting construction plate 202 will slowly tilt, causing the circular solid base 503 to slide a certain distance under its own weight; and because the two control buttons 505 are fixed... The rectangular pressing rod 506 is fixedly installed inside the U-shaped mounting frame 501 and slidably installed on the U-shaped mounting frame 501. The top of the rectangular pressing rod 506 is fixedly connected to the circular solid base 503. When the circular solid base 503 slides a certain distance under its own weight, the rectangular pressing rod 506 can press one of the control buttons 505. When one of the control buttons 505 is in the pressed state, the intelligent control panel 600 controls the two drive motors 106 to stop working, and the alarm inside the intelligent control panel 600 sounds an alarm. Furthermore, since each of the two lifting control wheels 103 is provided with a wrench insertion slot 1031, it is convenient for an external large wrench to be connected to the corresponding lifting control wheel 103. When the worm gear reducer 105 and drive motor 106 that have failed are removed, the construction personnel can use an external large wrench to adjust the angle of the corresponding lifting control wheel 103 appropriately, which is conducive to the straightening of the tilted lifting construction plate 202. Also, since the two emergency sprockets 104 are fixedly installed on the two lifting control wheels 103, it is convenient for the construction personnel to connect the lifting control wheels 103 through an external chain and two connecting emergency sprockets 104. When the worm gear reducer 105 and drive motor 106 that have failed are removed for repair, and the other drive motor 106 is working normally, the two lifting control wheels 103 rotate simultaneously under the action of the two emergency sprockets 104 and the chain, which is conducive to the normal movement of the lifting construction plate 202. Under the premise of not affecting the normal construction of the shaft, the damaged worm gear reducer 105 and drive motor 106 can be repaired in time.

[0033] The specific usage and function of this embodiment are as follows: In use, this invention first connects the shaft connecting frame 101 to the top of the elevator shaft using expansion bolts. Then, the intelligent control panel 600 is connected to an external power source. Afterward, workers enter the lifting construction platform 202, placing their feet on the top of the footrest disc 403. The intelligent control panel 600 controls the two drive motors 106 to operate. When the intelligent control panel 600 controls the two drive motors 106 to rotate forward, the lifting construction platform 202 moves slowly downward; when the intelligent control panel 600 controls the two drive motors 106 to rotate in reverse, the lifting construction platform 202 moves slowly upward, facilitating construction work at different heights within the shaft. When workers are working inside the shaft, they automatically separate from the footrest disc 403. Four rubber anti-slip blocks 404 brake the four rectangular sliding rods 301, ensuring the lifting construction platform 202 does not shake during construction, thus increasing stability. When one drive motor 106 stops working due to a malfunction, and the other drive motor 106 continues working normally, the lifting construction platform 202 will slowly... The circular solid base 503 slowly tilts, allowing it to slide a certain distance under its own weight. When the circular solid base 503 has slid a certain distance under its own weight, the rectangular pressing rod 506 can press one of the control buttons 505. When one of the control buttons 505 is pressed, the intelligent control panel 600 controls the two drive motors 106 to stop working, and the alarm inside the intelligent control panel 600 sounds an alarm. When the malfunctioning worm gear reducer 105 and drive motor 106 are removed, the construction personnel can... Adjusting the angle of the corresponding lifting control wheel 103 appropriately with an external large wrench helps to straighten the tilted lifting construction plate 202. When the worm gear reducer 105 and drive motor 106 that have failed are removed for repair, and the other drive motor 106 is working normally, the two lifting control wheels 103 rotate simultaneously under the action of the two emergency sprockets 104 and the chain, which helps the lifting construction plate 202 move normally. Under the premise of not affecting the normal construction of the shaft, the damaged worm gear reducer 105 and drive motor 106 can be repaired in time.
